Crash Tag Team Racing is a racing game for all the standard game consoles and the PlayStation Portable. Developed by Radical Entertainment, it was released in North America, Europe, and Japan in 2005. Crash Tag Team Racing is the third installment in the Crash Bandicoot racing games, succeeding Crash Team Racing and Crash Nitro Kart. Unlike the previous two, it combines the elements of platforming and racing games, with Crash being the playable character during the platforming segments of the game. Crash Tag Team Racing is both a platformer and a racing game, the racing segments featuring eight drivers racing in individual vehicles in an old dilapidated amusement park. Players can "clash" with an opponent during a race and fuse their cars together, with one player controlling the car, and the AI controlling the turret, a feature that has often been compared to Mario Kart: Double Dash!!
